SPECIFICATION forming part of Letters Patent No. 757,188, dated April, 12, 1904.

Application filed October 29,1903.

To all whom it may concern:

Be it known that I, THOMAS GooDALs, of Wadena, in the county of \rVadena, State of Minnesota, haveinvented certain new and useful Improvements in Pneumatic Straw-Stackers, of which the following is a specification.

The object of my invention is to provide a straw-stacking apparatus which will not break up the straws into short pieces in discharging them from the machine upon the stack, to the end that the stack will shed water better and the fiber of flax-straw be longer and more suitable for making tow.

A further object is to provide an easy-running straw-stacking machine that is simple in construction and can be readily attached to any style of separator.

The invention consists generally in various constructions and combinations, all as hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure l is a side elevation of a separator with my improvedstrawstacking apparatus applied thereto. Fig. 2 is a plan view of the same. Fig. 3 is a vertical section of the end of the separator and strawstacking apparatus, and Fig. 4 is a section on the line 1!; :1: of Fig. 3.

In the drawings, 2 represents a separatorcasing having the usual straw-rack 3, bolt 4, pan 5, and shoe 6, arranged beneath the dis- A fan 7 is arranged to create a current of air over the shoe (3 and past the discharge end of the pan 5 to separate the light chaff and refuse material from the grain. An \u'irightspout 8 is arranged at one end of the belt 4 a d communicates at its lower end with an air-trunk 5), arranged horizontally and iizonnnunicating at its outer end with aswiveled stacker-tube H). A plate 11 extends across the inner end of theair-trunk 9, dividing the same into an upper and lower passage, the former leading to the throat of the spout 8 and the latter to air-blast passages 12, that communicate with fan-cz-isings 13, inclosing fans 14, mounted on a shaft 15. The straw that falls upon the belt a is carried along to the spout 8and discharged therefrom into the air-trunk 9, Where it meets the blasts Serial No. 178,970. (No modelo of air from the passages 12 and is blown out through the stacker 2 without passing through the fan-casings. It follows, therefore, that the libers of the straw will not be broken, and it will require considerably less power to operate the fans than itwould where the straw is carried directly through the casings.

To carry away the chaff and light refuse material that collects beneath the belt t, 1 prefer to provide an auxiliary fan mechanism loca ted in the rear of the twin fans and arranged to discharge the chaff into the air-trunk 9, so that it will mingle with the straw and pass out through the stacker-tube to the stack. This chad-blowing apparatus consists, preferably, of a plate 16, arranged in the rear of the fancasings 13 and near the shoe (5 in position to receive the chaff and light refuse material that isscparated from the grain by the action of the fan 7. The inner end of the plate 16 is preferably provided with depressions 17, communicating through openings 18, arranged between and in front of the casings 13. A shaft 20 extends through the casing 19 and is provided with a fan 21, a driving-pulley 22, and a pulley 23, connected by a belt 24 with a similar pulley 251m theshal't'iS. All three fans are thus connected and will be operated siniultanemisly. A blast-passage 2h, closed except at its ends, is provided between the casings l3 and communicates at its inner end with the casing 1.) and at its forward end with the air-trunk J. The chail' and refuse material, therefore, that falls upon the plate 16 will These fans are made of any suitable size, ac-

able to preserve in an unbroken condition the iibers of the straw and render it more ea ily handled and better suited for feed and male ing tow.

.i clahn as. my invention l. The combination, with astackcntubc, of

IOO

' a stacker-tube connected with said trunk, aira trunk adapted to receive the straw and having air-passages at the sides, blast-fans com- Inunicating with said passages, a centrallyarranged air-passage leading into said trunk, a third blast-fan adapted to receive the chafl and communicating with said centrally-arranged passage.

2. The combination, with a trunk arranged to receive the straw and provided with a stacker-tube and having air-passages at its sides, of blast-fans connected with said pas sages, a centrally ari'anged airpassage between .said side passages, and a third blast-fan having a chaff-collecting plate and communicating with said centrally-arranged passage.

3. *In a separator, the combination, with a straw belt or carrier, of an air-trunk communicatingwith the discharge end of said belt,

" fans having air-passages leading into said airtrunk a third blast-fan between said firstnamed, fans and in front of the same and having an airpassage leading'into said trunk,

and a chaff-collecting plate partially inclosin'g said third blast-fan and communicatingflwith scribed.

, 5. In a separator, the combinationJ/with a shoe and a grain-pan, of a plate providednear said shoe, a fan-casing having openings 1111138 side walls to rece ve material from said plate,

a fan operating in said casing, a blast-passage the interior of its casing, substantially as de -f connected With said casing, an air-trunk into j which said blast-passage discharges, a stackertube connected with said trunk, fan-casings provided on each side of said air-blast passage and having passages also communicating with,

said air-trunk,'blastfans provided-in said lastnamed casings, a straw-conveying spout provided above said fan-casings and having its discharge end leading into said air-trunk, and] a straw-conveying belt' or carrier having its discharge end near the receiving end of said spout, substantially as described.

6. The combination, with a stacker-tube, of a trunk adapted to receive the straw and having two air-passages, blast-fans communicating with said passages, a third air-passage leading into said trunk, and a third blast-fan adapted to receive the chaff andcommun'icat ing with said third passage.

1n witness whereof I have hereunto set my hand this 23d day of October, 1903.
